It is what the gay scout should have done but no, they want to ruin traditional scouts for their own selfish goals.
Right on the money. They want access to the boys so as to be able to recruit and molest them. They also hate the things BSA stands for so they seek to destroy the organization.
Bad news for them is that as the organization shrinks or dissolves their access to the boys will go away. "Where did all my boy toys go? How could this happen? We only wanted to teach them to give themselves over to absolute pleasure! What happened?"
That's one aspect but IMO they are attempting to give their way of life and their lifestyle a form of legitimacy by forcing a truly decent and legitimate organization to accept and therefore condone them and their aberrant and self-destructive lifestyle.
I too hope more church and other BSA sponsoring groups pull out of supporting the BSA now.
